I really like the 510 internals. The Fog has a learning curve, but after a few mishaps, I am getting such better flavor out of my LR 510 than ever before. Not having to to drip on my ego makes it all worth it. Any fiddling with it is by no means equal to all the dripping I had to do. If you are on the fence, you just haven't tasted your favorite liquid on it. Tell Bruce to put in an order for some more, and make the purchase. I think it looks sweet on any chrome ego.
